locus-tag	class	description
HOR21_gp057	COG0846	NAD-dependent lysine deacetylase and desuccinylase that specifically removes acetyl and succinyl groups on target proteins. Modulates the activities of several proteins which are inactive in their acylated form
HOR21_gp079	COG5405	Protease subunit of a proteasome-like degradation complex believed to be a general protein degrading machinery
HOR21_gp081	COG1702	phosphate starvation-inducible protein PhoH
HOR21_gp085	COG1091	dTDP-4-dehydrorhamnose reductase activity
HOR21_gp091	COG0484	heat shock protein binding
HOR21_gp095	COG0209	Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides
HOR21_gp198	COG0210	DNA helicase
HOR21_gp202	COG1328	CTP reductase activity
HOR21_gp216	COG3853	Toxic anion resistance protein (TelA)
